Study On Vibration Control Of Forging Hammer Foundation

Forging hammer is an important equipment for processing parts with forging in manufacturing production, however, the immense impact loads when working induce vibration which is produced by anvil,chock,foundation and the neighboring buildings. And for this reason, a series of problems of industrial production and people's living have appeared.In the 'anvil-foundation-groundwork' system , the bouncing dynamic model, namely the bouncing dynamic model with damped two-degrees of freedom, is established to get the vibration isolation performance best. It is effective to optimize math model and the design result so as to frequency domain transfer function curve more gently by setting reasonable initial value and objective functions. For system with periodic vibration, this method not only eliminates resonance but also refrains from skipping suddenly during starting on and off , which prolong service life of equipment and prevent asymmetrical subsidence about groundwork caused by mutative vibration.During verification optimization results, complicated proof procedure about the numerical analysis is avoided. Based on the features of frequency domain function and time domain function, both optimization results and original ones are visually simulated .It is observed that the more quickly the vibration damping is , the more smooth the vibration of foundation is. Foundation stress restores smoothly for a shorter time. Vibration transfer ratio declined 11.6% compared to its original after optimization, which proves that the foundation of forging hammer gets more isolation effect, thus let the designed results be more tally with practice. Practical values on vibration isolation can be presented.
